7 Typical Antenna Configuration (Gate Antenna with two Antennas)
Typical Antenna Configuration
The standard configuration of a gate with three-dimensional tag orientation consists of one
ID ISC.ANT1710/690-A Crystal Gate Excellence with reader and multiplexer and one ID ISC.ANT1710/690-B
Crystal Gate Excellence. If a tag moves horizontally through the gate, it can be read at least once. This
ensures high reliability of the antenna system.
7.1 Project Notes Antenna
The described antenna configuration allows the detection of a tag moving on a horizontal line through the
reading area of the gate. The tag orientation is arbitrary. The tags are detected along a horizontal axis of
motion in certain areas within the antennas. The area of detection depends on the tag orientation.
The size of the three-dimensional reading area of the antennas is shown in the sketch below.
Fig. 10: Capture area and tag orientation
NOTE:
•
Note that the entire reading area of the antenna gate is larger than the three-dimensional area
shown in the drawing (
•
Fig. 11). This means there are tag orientations in which the tag can be detected outside the
reading area.
•
To achieve optimal performance, the reader must be configured and operated in one of the
Reader Automatic Modes (Buffered Read, Notification or Scan Mode).
